Egg laying commences 10-12 weeks after the initial infection, which is important to note when using fecal eggs counts to diagnose infection. They are voracious feeders and migrate through the liver parenchyma to reach the bile duct, where they mature.
There are also between 2.5 and 17 million reported cases of human fasciolosis from eating aquatic vegetation (mainly wild watercress) contaminated with infective metacercariae ( Ghildiyal et al, 2014). Fasciolosis does not just afflict sheep but all grazing animals are susceptible to infection including cattle, deer, rabbits and horses. In Europe the snail species naturally infected with Fasciola hepatica (Liver fluke) is Galba trunculata (previously known as Lymnaea trunculata), and in the USA multiple fresh water snail species belonging to the genus Lymnaea have been reported to harbor infection ( Dunkel et al., 1996). Climatic and hydrological factors play an important part in the epidemiology of the disease which is directly linked to the habitat of the intermediate mud snail host. Opisthorchis felineus can be found in Florida, Hawaii, South America and parts of continental Europe.Fasciolosis is an economically important and potentially fatal disease of sheep which can be associated with particular regions throughout the world directly linked to the habitat of an aquatic mud snail. Treatment is Praziquantel to kill the flukes and supportive care. Low numbers may nor produce symptoms at all, however a heavy infestation may produce the following symptoms:įlukes can cause a blockage at the head of the pancreas resulting in exocrine pancreatic insufficiency which can produce greasy fecesĭiagnosis is made by examination of the feces for eggs as well as tissue and fluid samples from the liver. Once inside the cat, the prey breaks down and the adult flukes pass through the stomach and to the bile duct and liver. Cats become infected when they eat an infected fish or reptile.
#FLUKE WORM FREE#
Once in the snail they undergo further developmental changes, leaving the snail as cercaria (a second free swimming larval stage) and infecting fish, frogs or lizards.
Eggs in the water hatch into the miracidium form (free swimming) which infect passing snails. Opisthorchis felineus is a fluke which infects cats in much the same way as the other flukes listed above.
Many times a liver problem can go undiagnosed without knowing the cat has Liver Fluke Worms. If your cat lives outside or in contact with frogs and lizards please read this. Liver Fluke Worms in cats will KILL them if left untreated! This is good reason not to feed your cat raw fish or lobster, keep them safe from eating lizards and frogs outside if you live in a tropical place like Florida, Hawaii and central America… They don’t know everything and many don’t think, let along think out of the box! They get complacent! The incompetence of some allopathic vets is mind boggling to me! Get yourself educated…don’t think everything you hear from a vet is truth. If he had been diagnosed from the start and the samples of worm I kept showing the vet here, he would have been able to live a much longer life. If left undiagnosed like it was in our beloved Caesar it will kill them. It hitches a ride with an intermediate host, typically the land snail, which is then ingested by another intermediate host, such as the lizard and frog. The cat liver fluke, also known as Opisthorchis felineus, is a trematode parasite that lives in water.
